Overwrite the default configuration file at C:\Program Files\Cloudbase Solutions\Cloudbase-Init\conf\cloudbase-init.conf with the following

[DEFAULT]
username=Admin
groups=Administrators
inject_user_password=true
plugins=cloudbaseinit.plugins.windows.sethostname.SetHostNamePlugin,cloudbaseinit.plugins.windows.createuser.CreateUserPlugin,cloudbaseinit.plugins.windows.networkconfig.NetworkConfigPlugin,cloudbaseinit.plugins.windows.sshpublickeys.SetUserSSHPublicKeysPlugin,cloudbaseinit.plugins.windows.extendvolumes.ExtendVolumesPlugin,cloudbaseinit.plugins.windows.userdata.UserDataPlugin
network_adapter=
config_drive_raw_hhd=true
config_drive_cdrom=true

Disable Windows Firewall or setup the services that you want to allow for a finer control (this was just a rough test)

Apply customization to image
Install packages, add users, modify configurations, etc.
Run Windows Update
Run Sysprep:
C:\Windows\System32\sysprep\sysprep.exe /generalize /oobe /shutdown

Convert disk image into qcow2
Sorry to get into Ubuntu.. We need some what. VirtualBox only supports Qcow images, not Qcow2, so we'll use qemu-img to convert the image to Qcow2 for use with OpenStack. as below
qemu-img convert -f qcow -O qcow2 windows.qcow windows.qcow2
Reboot the VM
Now import the qcow2 image in glance
# glance image-create –name window –is-public=true –disk-format=qcow2 –container-format=bare –file (location of qcow2 image that you want to import into glance ).

please comment with your experience
